Stuffed Bell Peppers with Quinoa and Black Beans

Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish or a similar-sized casserole dish.

Place the bell pepper halves in the prepared baking dish, cut side up. Bake for 15-20 minutes, or until slightly softened.

While the bell peppers are baking, prepare the filling. In a large skillet, heat the olive oil over medium heat. Add the chopped onion, and cook for 3-4 minutes, until softened. Add the garlic, and cook for another 1 minute, until fragrant.
